Function FindFirstIdentity

expr/node.go:340–346

FindFirstIdentity Recursively descend down a node looking for first Identity Field min(year) == year eq(min(item), max(month)) == item eq(min(user.last_name), max(month)) == user.last_name

(node Node)

//     eq(min(user.last_name), max(month)) == user.last_name

}

// FindAllIdentityField Recursively descend down a node looking for all Identity Fields
